IMPROVEMENT IN LUBRICATORS FOR STEAM-ENGINES.

Specification forming part of Letters Patent No. 53,l95, dated March 13,1866.

To all whom it may concern:

Be it known that I, JOHN STORER, of the city, county, and State of NewYork, have invented a new and useful Improvement in Lubricators; and Ido hereby declare the following to be a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, forming a part of this specification, in which- Figure lis acentral vertical section of .a lubricator constructed according to myinvention. Fig. 2 is an inverted plan of the cover ot same; and Fig. 3is a plan view ofthe cup with the cover removed.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention relates to lubricators for the use either of oil or ot'tallow or suet.

lt consists in a certain construction ot' and mode of tting and securinga removable cap or cover, whereby provision is made for its speedyattachment and removal.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A is the shell, cup, or reservoir of the lubricator, intended-to beattached at the,bottoni to the steam-cylinder or other part of an engineor other machine or apparatus to be lubricated, with an interposedglobe-valve or cock, I, to regulate the supply ot' lubricating material.

D is the removable cap or cover, which gives .t finish to the upper partof the instrument, and serves as an abutment for the screw F, which isturned by a hand-wheel, Gr, or other handle to operate an inner lid orvalve, E, by which the top ofthe cup or reservoir is closed steam andair tight.

Around the upper part of the exterior of the cup A there is a groove, a,and Athe projection or ilange B above this groove has provided in it twoopenings, e e, Fig. 3, each extending about one-t'ourth of the way roundthe cup for the passage of two projections, O C, Figs. 1 and 3, providedaround the interior of the bottom of the removable cap D. By placing thecap on the top of the cup with the projections O C opposite the openingsc e, and dropping it down to bring the projections C C into the grooveaa., and then turning the cap a short distance to bring the saidprojections under the flange B and against a stop, b, Fig. 3, in thegroove a, the cap is attached t0 the cup.

The screw F is fitted to a female screwthread in an opening in thecenter ofthe cap D, and it has the inner lid or valve, E, attached to itconcentrically in such manner that the said lid or valve will be removedand replaced with the cap D, but that the screw may turn freely in thesaid lid or valve.

In the top of the cup A there is a groove, d, fitted with soft metal toform a seat, on which the lid or valve E may be made to fit air andsteam tight when the screw F is screwed down after the attachment of thecap D.

'Io remove the cap D and air and steam tight lid or valve E, it is firstnecessary to give a partial turn backward to the screw for the purposeof loosening the cap D, then to turn the cap till the projections C Ccome opposite the openings e e in the top ange, and lift oft' the cap.

When the cap has been put on again and turned to bring the projections C(l under the iiange B a slight turn of the screw secures the cap, and atthe same time brings the lid or valve E tight on its seat. This removaland replacement ot the cap and lid can be effected more expeditiouslythan the removal and replacement of any ofthe covers in common use onlubricators.

H is a small cylinder ot' sheet metal with perforated sides, arranged inthe center of the lower part of the cup A over the outlet-opening. llhepert'orations in this cylinder are small, but so numerous that theiraggregate area is equal to that of the full opening of the valve I, yetthey will not allow the lubricating material to pass them in bulk, andwill prevent any choking up -of the outletpas sage.

The periphery of the cylinder may be covered with cloth or lamp-wick, orother fibrous material, which will form a perfect strainer and make thelubricating operation very gradual without diminishing the opening ot'the valve I or outlet-passage.

rlhe cylinder ai'ords better provision for the application of a brousstrainer or pereolater tion with each other and with the groove a thanis afforded'by any other form of perfoand openings@ e in the upper partof the cup, rated surface. substantially as herein Specied.

What I olairn as my invention7 and desire JOHN STORER. Y to secure byLetters Patent, is- Witnesses w The cap D, with projections C C, thevalve J. W. COOMBS, or inner lid, E, and the screw F, in combinal A. LECLERC.
